That alone is worth pausing on. Islands of this size do not typically generate much in the way of formal routeways, and the presence of a recognised road or trackway suggests a history of movement and use that goes well beyond the occasional visit.

Inchagoill, whose name derives from the Irish Inis an Ghaill, meaning roughly the island of the foreigner or the devout stranger, has long been associated with early Christian activity. It is home to two ancient churches, one of which, the Saints' Church, contains the Lugnaedon Stone, one of the oldest inscribed Christian monuments in Ireland outside of ogham script, ogham being an early medieval alphabet typically carved along the edges of standing stones. A road or trackway on such an island implies an organised community moving between fixed points, whether between the churches, a landing place, or other features of daily life that have since disappeared from the record. The island is uninhabited today, which makes the presence of any formal routeway a quiet but telling detail about how thoroughly it was once occupied and managed.
